eBay Inc. v. MercExchange (2006)
Pre-eBay, an injunction was a kill switch a patent holder could threaten. Post-eBay, the worst is monetary damages — and for an NPE that wants license fees anyway, the four-factor test usually fails on the irreparable-harm prong.
Markman v. Westview Instruments, Inc. (1996)
Claim construction is exclusively the court's job. The Markman hearing is the most consequential single ruling in nearly every patent case — and a defendant's best chance to end the litigation before trial.
KSR International v. Teleflex (2007)
Pre-KSR, an obviousness rejection required explicit teaching, suggestion, or motivation in the prior art. Post-KSR, common sense, design needs, and predictable variations all do the work — and most patents don't survive.
The Patent Scam (2017): a documentary on the patent troll industry
Most people learn about patent trolls only when they get sued by one. The Patent Scam does the work of making the problem concrete before that happens.
District court vs. PTAB: where to fight a patent challenge
